I think NOF was under the impression that Dennis Allen and Mickey care what they say so they started being super negative about the team. I agree that Brooke was the most professional of everyone.
I've never seen Nick or Mike be super negative. In fact, many accused them of carrying the teams' water until very recently. I think they both report what they know and give pretty even handed opinions. In fact, I think Nick often times goes out of his way to not be too negative and just tell us what is going on.
